Description

Technical Field

[0001] This invention relates to the field of scaffolding installation technology, specifically to a quick-assembly disc-lock scaffolding. Background Technology

[0002] Disc-lock scaffolding is widely used on construction sites due to its advantages such as high load-bearing capacity, high assembly and disassembly efficiency, and standardized components. In a typical disc-lock scaffolding structure, horizontal bars are connected to connecting discs on the vertical bars via plugs at their ends, and are locked in place using wedge pins inserted into aligned holes. However, existing disc-lock scaffolding typically relies solely on the simple insertion of wedge pins into the holes at the connection points between horizontal and vertical bars for positioning. In actual use, due to factors such as construction vibration, component gaps, or accidental human contact, wedge pins are prone to loosening or even falling out of the socket, leading to connection failure and posing a safety hazard. In addition, although some existing structures have been equipped with anti-detachment measures, they are often complex in structure and inconvenient to operate, affecting the efficiency of rapid assembly and disassembly of scaffolding.

[0003] Therefore, a quick-assembly disc-lock scaffolding is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-assembly disc-lock scaffold.

[0005] The objective of this invention is achieved through the following technical solution: a quick-assembly disc-lock scaffold, comprising: a footboard, a threaded rod, and an upright. A horizontal rod is mounted on the upright via a connecting plate. A plug that is installed on the connecting plate is fixedly connected to the end of the horizontal rod. The plug and the connecting plate have mating insertion holes. A wedge-shaped pin is inserted into the insertion hole. A sliding plate is horizontally inserted into the groove at the top of the wedge-shaped pin. A rotating plate is hinged to the middle of the sliding plate. Multiple interconnected hinge plates are hinged between the rotating plate and the horizontal rod. The rotating plate rotates to a horizontal state to cooperate with the sliding plate and insert into the groove. It also includes a connector for inserting a wedge-shaped pin, which is inserted into a horizontal rotating plate and a sliding plate; this achieves double locking of the wedge-shaped pin and the connecting plate, effectively preventing the wedge-shaped pin from falling off. The structure is compact, the operation is simple, and the safety and reliability of the scaffolding connection nodes are improved.

[0006] As a further description of the above technical solution: Multiple sets of limiting plates are fixedly connected to the edge of the connecting plate. Each set of limiting plates engages with the plug and corresponds to the position of the plug hole on the connecting plate. The limiting plates serve to guide and prevent misalignment, ensuring that the plug and the connecting plate are quickly and accurately aligned, avoiding plug misalignment, and improving installation efficiency and connection accuracy.

[0007] As a further description of the above technical solution: Both the rotating plate and the sliding plate are provided with locking holes for insertion and engagement of the connector. The locking holes enable direct positioning of the connector, ensuring reliable locking and preventing relative movement between the rotating plate and the sliding plate, thereby further enhancing the anti-disengagement capability of the wedge-shaped pin.

[0008] As a further description of the above technical solution: The rotating plate is a T-shaped plate, and the locking hole is located in the middle of the rotating plate and the sliding plate. The plate structure increases the rigidity and stability of the rotating plate, and the central opening facilitates the vertical insertion of the connector, avoids skewing, and improves the locking firmness.

[0009] As a further description of the above technical solution: The connector includes a locking screw threadedly connected to a wedge-shaped pin. The bottom of the locking screw is fixedly connected to a plug rod inserted into a locking hole. The plug rod is precisely positioned and locked by thread drive, which saves effort in operation. After locking, it can prevent the plug rod from coming out on its own and has a self-locking function.

[0010] As a further description of the above technical solution: The bottom end of the insertion rod is provided with a first anti-detachment plate inserted into the locking hole, and the end of the sliding plate is fixedly connected with a second anti-detachment plate. The size of the second anti-detachment plate is larger than the size of the sliding groove, which effectively prevents the insertion rod from accidentally detaching from the sliding plate and significantly improves the structure's earthquake resistance and impact resistance.

[0011] As a further description of the above technical solution: A collar is fitted onto the horizontal bar, and a protective sleeve that mates with a wedge-shaped pin is fixedly connected to the collar. The end of the protective sleeve mates with the vertical bar. The protective sleeve provides physical protection for the wedge-shaped pin and the connector, preventing external collisions, foreign objects from entering, or accidental human contact that could lead to unlocking, while also further enhancing the overall stability of the node.

[0012] As a further description of the above technical solution: The bottom of the protective sleeve and the outer surface of the plug are provided with mutually matching inclined surfaces. An anti-slip layer is provided on the inclined surface of the protective sleeve. The inclined surface matching design makes the protective sleeve and the plug fit tightly together. The anti-slip layer prevents the protective sleeve from sliding backward on its own, ensuring the stability of the protective position, and improving the vibration resistance of the overall node.

[0013] Compared with the prior art, the advantages of the present invention are as follows: This application provides a sliding groove at the top of the wedge-shaped pin, along with a horizontally insertable sliding plate and a hinged rotating plate. The rotating plate and sliding plate are then locked inside the wedge-shaped pin by a connector, forming a multi-limiting structure that effectively prevents the wedge-shaped pin from coming loose from the socket, significantly improving the stability and safety of the connection node.

[0014] The rotating plate is linked to the horizontal bar via a hinge plate. With simple operation, the rotating plate can be aligned with the sliding plate and inserted into the slide groove. Then, the locking screw can be turned to lock it in place. No additional tools or complicated steps are required, which enables quick assembly and disassembly and improves construction efficiency.

[0015] A sliding protective sleeve is fitted on the horizontal bar to cover and protect the wedge-shaped pin and connector, preventing external debris from entering or accidental collisions from causing unlocking; the inclined surface at the bottom of the protective sleeve matches the plug and has an anti-slip layer, further enhancing the positioning and protection effect.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1-9The diagram shows an embodiment of a quick-assembly disc-lock scaffolding provided by the present invention, including: a footboard 1, a threaded rod, and an upright 2. A horizontal rod 4 is installed on the upright 2 via a connecting plate 3. A plug 5, which is installed on the connecting plate 3, is fixedly connected to the end of the horizontal rod 4. The plug 5 and the connecting plate 3 have mutually cooperating insertion holes 6. A wedge-shaped pin 7 is inserted into the insertion hole 6. A sliding plate 9 is horizontally inserted into the sliding groove 8 at the top of the wedge-shaped pin 7. A rotating plate 10 is hinged to the middle of the sliding plate 9. Multiple interconnected hinge plates 11 are hinged between the rotating plate 10 and the horizontal rod 4. The rotating plate 10 rotates to a horizontal state and cooperates with the sliding plate 9 to be inserted into the sliding groove 8. In this application, the wedge-shaped pin 7 is always connected to the horizontal rod 4 and will not detach or fall off. It also includes a connector for inserting the wedge-shaped pin 7, which is inserted into the horizontal rotating plate 10 and the sliding plate 9. The plug 5 at the end of the horizontal rod 4 mates with the connecting plate 3 on the vertical rod 2. After the plug 5 is aligned with the insertion hole 6 on the connecting plate 3, the wedge-shaped pin 7 is inserted into the insertion hole 6. The sliding plate 9 is horizontally inserted into the groove 8 at the top of the wedge-shaped pin 7. The rotating plate 10 is hinged to the middle of the sliding plate 9. The rotating plate 10 and the horizontal rod 4 are connected by multiple hinged plates 11. By pushing the hinged plates 11, the rotating plate 10 is rotated to a horizontal state and inserted into the groove 8 together with the sliding plate 9. Finally, the connector is inserted into the rotating plate 10 and the sliding plate 9 to lock the wedge-shaped pin 7 and the connecting plate 3.

[0019] Multiple sets of limiting plates 12 are fixedly connected to the edge of the connecting plate 3. Each set of limiting plates 12 is engaged with the plug 5, and each set of limiting plates 12 corresponds to the position of the socket 6 of the connecting plate 3. During installation, the plug 5 is clamped and positioned by the limiting plates 12 to ensure that the socket 6 is accurately aligned.

[0020] Both the rotating plate 10 and the sliding plate 9 are provided with locking holes 13 for insertion and engagement of the connector. The connector passes through the locking holes 13 on the rotating plate 10 and the sliding plate 9 to lock the two together.

[0021] The rotating plate 10 is a T-shaped plate, and the locking hole 13 is located in the middle of the rotating plate 10 and the sliding plate 9. The rotating plate 10 is designed as a T-shaped plate, and the locking hole 13 is set in the middle of the rotating plate 10 and the sliding plate 9 to ensure that the force is even when the connector is inserted.

[0022] The connector includes a locking screw 14 that is threadedly connected to the wedge-shaped pin 7. The bottom of the locking screw 14 is fixedly connected to a plug rod 15 that is inserted into the locking hole 13. When the locking screw 14 is rotated, the plug rod 15 is inserted downward into the locking hole 13 of the rotating plate 10 and the sliding plate 9.

[0023] The bottom end of the insertion rod 15 is provided with a first anti-detachment plate 16 that is inserted into the locking hole 13. The first anti-detachment plate 16 prevents the insertion rod 15 from detaching from the wedge-shaped pin 7. The end of the sliding plate 9 is fixedly connected with a second anti-detachment plate 17. The size of the second anti-detachment plate 17 is larger than the size of the sliding groove 8. The bottom end of the insertion rod 15 is provided with the first anti-detachment plate 16, so it is not easy to detach after being inserted into the locking hole 13. The end of the sliding plate 9 is provided with the second anti-detachment plate 17, which is larger than the size of the sliding groove 8, to prevent the sliding plate 9 from completely sliding out of the sliding groove 8.

[0024] A collar 18 is fitted onto the horizontal bar 4. A protective sleeve 19 that engages with the wedge-shaped pin 7 is fixedly connected to the collar 18. The end of the protective sleeve 19 engages with the vertical bar 2. Inside the protective sleeve 19 (near the vertical bar 2), a magnetic plate that magnetically engages with the vertical bar 2 is installed. After installation, the collar 18 is slidable to move the protective sleeve 19 to the outside of the wedge-shaped pin 7, and the end of the protective sleeve 19 engages with the vertical bar 2.

[0025] The bottom of the protective sleeve 19 and the outer surface of the plug 5 are provided with inclined surfaces 20 that cooperate with each other. An anti-slip layer is provided on the inclined surface 20 of the protective sleeve 19. The top of the wedge-shaped pin 7 has a T-shaped structure. After the protective sleeve 19 slides into place, the inclined surface 20 fits against the plug 5, and the anti-slip layer increases the friction.

[0026] Working principle: By inserting the U-shaped plug 5 between the two limiting plates 12 and aligning the plug 5's socket 6 with the connector plate 3's socket 6, multiple hinge plates 11 are moved, the rotating plate 10 is rotated, and the sliding plate 9 moves along the slide groove 8. When the rotating plate 10 switches to the horizontal state, the rotating plate 10 is horizontally inserted into the slide groove 8; the rotating plate 10 and the sliding plate 9 are horizontally inserted into the slide groove 8. At this time, the locking hole 13 on the sliding plate 9 and the locking hole 13 on the rotating plate 10 are aligned and located directly below the locking screw 14. At this time, rotate the locking screw 14 to insert the insertion rod 15 into the locking hole 13 on the sliding plate 9 and the rotating plate 10, thereby completing the connection and fixation of the wedge pin 7 with the connecting plate 3 and the plug 5.

[0027] Finally, the protective sleeve 19 is moved by the sliding collar 18 to engage the protective wedge pin 7.
